MS-DOS (short for Microsoft Disk Operating System) is the DOS-type operating system developed by Microsoft for IBM PC first, then for PC compatible. It is a system operating in real mode, single task and single user, and equipped by default with a command line interface. From the 1980s to the early 1990s, it was the most used system on PC compatible, before being gradually replaced by more advanced operating systems, including Windows. Its development is now stopped.
